Range and Habitat

Crossbill: Resident throughout the UK and Ireland. Nomadic in nature, it goes where ever there are good cone crops. Preferred habitats include coniferous forests, plantations and mixed woodlands; visits ornamental evergreens in winter. Norway spruce, sitka, and larch trees are favoured.

SONGS AND CALLS

Voice Text

"chip", "chip", "chip", "chip"

INTERESTING FACTS

The Crossbill is so dependent upon conifer seeds it even feeds them to its young. It can breed any time it finds a sufficiently large cone crop, even in the depths of winter.

They show a great deal of variation in bill shape and voice, and may in fact be composed of several different species.

A group of crossbills are collectively known as a "crookedness" and a "warp" of crossbills.

FAMILY DESCRIPTION

Finches (Fringillidae)

ORDER

Also known as perching birds, the order PASSERIFORMES (pronounced pas-ser-i-FOR-meez) is composed of one hundred and eighteen families of birds, among which are the insectivorous warblers and the seed-eating finches.

FAMILY TAXONOMY

The Fringillidae (pronounced frin-JIHL-lih-dee) is a widespread bird family found on most continents and includes two hundred and seven species of finches in thirty-nine genera (IOC World Bird List, version 2.3).

EUROPE

Thirty-four species of finches in thirteen genera have occurred in Europe. These include familiar feeder visitors such as goldfinches and siskins, the crossbills, and the massive-billed Hawfinch.

KNOWN FOR

Finches are known for their seed-eating behaviour and cheery songs; characteristics that facilitated and popularized the domestication of the Island Canary. Finches such as White-winged Crossbills are also known for their “irruptive" migrations in search of food sources that can make them locally common one winter and absent the next.

PHYSICAL

Finches are primarily small birds with stout, short bills adapted to cracking open seeds and have short legs for a mostly arboreal lifestyle. Many species also have slightly forked tails and long wings useful for the large amount of flying needed to find seeding plants.

COLORATION

European finches are generally plumaged in shades of red, yellow, brown, grey, and dull green. Male finches are more brightly coloured than females; the pinkish-red, grey, black, and white plumage of male Bullfinches being especially striking.

GEOGRAPHIC HABITAT

Finches in Europe occupy forest and non-forest habitats, coniferous forests being favoured by some species. The non-forest niche is filled by a variety of species including goldfinches, the Linnet, Twite, and the Trumpeter Finch.

MIGRATION

Most finches are adapted to cold weather and only migrate when seed crops on their breeding grounds become scarce. An exception to this is the Common Rosefinch which migrates from north-eastern Europe to India for the winter.

HABITS

Members of the finch family are very social birds typically found in flocks outside of the breeding season. Most finches forage for seeds in trees and bushes although a few species take some insects and forage on the ground.

CONSERVATION

While finches in Europe are doing quite well, most members of this family native to the Hawaiian Islands are highly endangered with many having already gone extinct and others in decline because of their high susceptibility to introduced diseases such as avian malaria and changes to the native forests they inhabit.

INTERESTING FACTS

The aptly named crossbills have curious curved bills with crossed tips. Although it looks more like a bill deformity than a useful tool, this specialized bill shape is perfect for extracting seeds from pine cones.

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters
of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus)
and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante
(2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42
(Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported
by the A.O.U from 2003 through 2006.

The Integrated Taxonomic Information System (ITIS) was established in the mid-1990 s as a cooperative project among several federal agencies to improve and
expand upon taxonomic data (known as the NODC Taxonomic Code) maintained by the National Oceanographic Data Center (NODC), National Oceanic and Atmospheric
Administration (NOAA).

To find the ITIS page for a bird species go to the ITIS web site advanced search and report page at http://www.itis.gov/advanced_search.html.
You can enter the TSN or the common name of the bird. It will return the ITIS page for that bird. Another way to obtain the ITIS page is to use
the Google search engine. Enter the string ITIS followed by the taxonomic ID, for example "ITIS 178041" will return the page for the Allen's Hummingbird.
